A ORNEY Patented Oct. 19, 1943 UNITE D STATES PATENT] OFFICE r 2,332,342 l v 7 com? CLUB Q Milton B. Reach, Springfield, Mass. 7 Application March 8, 1940, Serial No. 322,885 13 Claims. (01. 273 77 I This invention relates to improvements in golf clubs, and particularly golf irons.

Heretcfore a number of .problems have been encountered or have prevailed in connection with the manufacture of golf irons. For example, there are many special requirementsand features in golf clubs, such as: light, medium or heavy club heads, depending somewhat upon the strength and desire of theplayer; weighting of club heads toward the toe or heel in order to overcome a hookv or slice playing characteristic inherent in individual players or in certain types of clubs as handled by certain players; flat and upright lies to the club heads depending upon the angle relative to the ground which the player likes to have the golf club shaft when addressing and hitting the ball. 7

Heretofore these requirements have necessitated the manufacture of special golfcl u bs, or the production of small quantities of regular clubs embodying one or more of these requiremerits in solid club heads, which, in many instances, took a number" of weeks or months to process through the factory. For example, if a person desired a set of golf irons with an upright lie (shaft closer to the perpendicular than the average) if the store, pro or factory did not have the same in stock the factory would have tostart with forgings of the desired shape and process a set or sets of clubs through to completion. The latter would require a number of weeks to process through the factory unless ma'de special, and if made special such a set would disrupt the reg ular flow of production and result, indirectly at least, in excess manufacturing costs. Similar disadvantages occur if a player desires a set of irons which are heavier or lighter than those which the store or pro ordinarily carries in stock or which happen to be out of stock.

Although there have been some proposals in the past to weight golf woods no practical pro-' posals have been made in connection with the weighting of irons because of the narrow blade.

It is a'very important object of the present invention to provide golf irons which overcome the abcvementioned disadvantages prevalent with present'day types of golf irons; to wit, provide: a golf iron whch may have divers'li'es; golf irons which may have light, medium or heavy heads; golf irons in which the weighting toward the center, toe of heel may be effected with ease.

One feature resulting from the attainment of these objectives includes theprovision of novel bottom plates which may be secured to the lower side of the blade in such a manner as tp proyi de divers lies.. One such embodiment includes a re-t versible plate which in one position gives an upright lie to the club and in another position gives a'low lie thereto. 1 s

The foregoing represent real advantages to players, stores, pros and factories; to the player because he can havea set of irons with the ty'pe of lie which meets his exacting. requirements; to. the store and pros because itwillb'epossibleto quicklyjconvert aset of low 'lie irons to a set of upright lie "irons, 'orfvicefversa; to the-factory because it may process a very large number'fof i golf irons practicallyto the point of completion and then merely effect afinal assembly of the particular, forms of bottom plates, to the, lower part of the clubs in order toylllect incomingor-. ders for low or upright lie clubs; v

Heretofore the manufacturer ,might have a, large run of uprightlie'clubs processed, in stock or practically tothe point of completion, and if he receivedforders for low lie clubs it would'be necessary to start a new lot of clubs at theforg-, ing'shop and perhaps .lose as. much as six or eight Weeksbefore deliveries'of the latter type. With the presentinvention he could immediately make shipment of either upright,,,low orother lie clubs, With the old type of manufacture, wherein] solid iron heads were used, it, Was, veryioften necessary for a manufacturer to have a fvery large inventory, ,viz., stock .a large, number of upright and low lie clubs, in an eifortto meet.

field'requirements expeditiously. With the pres;

ent invention it is possible for a manufacturer to greatly reduce his inventory and to thereby increase his profits. r

There have been efforts in the past to provide single'irons with adjustable faces or the like, Howeven'most of these prior proposals included flimsy-V or necessarily weak pivoted connections at the hosel, between'thehosel orflshaft and the blade; which quickly loosened. This weakness is 'apparent when it is realized that there have been many such proposals, and .although'millions of golf clubs are manufactured each year such pivoted joint structures (for adjusting loft or face) have not come into general use.

The divers lies are achieved according to the present'invention with afsturdy shock absorbing structure. I ,7 l

Heretoforejthere have been prop osals for wieghting golf woods. Because of the large mass in the headof a golf wood no special problems were involved. However, because of the relatively small mass in a. golf iron special problems are involved'in elfectingjva weighting. Most prior efforts in this direction in connection with golf irons have been to build the weight into the solid forging. For example, a manufacturer might make up sets of irons to the maximum usual weights and if he receives an order for a medium or a light weight head he might have a certain amount of the bulk of the club ground or polished from the head. However, such practice, depending upon where most of the weight was removed, would very often shift the center of gravity appreciably and result in unbalanced or nonuniform clubs in a given set.

It is an important object of the present invention to provide golf irons which may be manufactured substantially to the point of completion and with which the manufacturer can in a final step provide customers or the trade generally with golf clubs of either light, medium or heavy weight of uniform head balance throughout a set.

A complemental object is the provision of golf v club weighting which may be distributed toward the center, toe or heel at will in order to build certain playing characteristics into a set of golf irons.

Features resulting from the attainment of the foregoing weighting objects include the provision of a bottom plate for the lower section of the golf club or golf club head with special means for adding and/or taking weight from. the golf club head near the sweet spot thereof, and to effect weighting toward the heel or toe of the club at will.

Other features in connection with the weighing include the provision of novel structure whereby it is not necessary to use drills or other special tools in order to effect a desired weighting of the club; weighting means which are located at or very near the normal sweet spot of the club head; structural arrangements wherein the club head proper serves to lock or hold weighting slugs in the bottom plate; and a bottom plate and holding means therefor adapted to translate a striking force into an arcuate line of force, whereby the load may be dissipated and lightened.

In the general use of golf irons in the fairways and rough stones are very often encountered or struck at the time of the swing. I Because of the metal head and usual metal connection between the head and the shaft an adverse vibration or shock is passed along to the hands of the player.

It is an object of the present invention to provide means to prevent or minimize this adverse condition.

A feature resulting from the attainment of this latter objective includes the provision of an insulator between the lower edge of the club and the head proper. In its preferred form. this insulation is vertically arranged in the club head in order to take the shock in a tilting direction.

In order to achieve a sweet feel in a golf iron when a ball is struck (viz., not cause excessive vibration or chatter through the shaft) it is desirable to have the head made of a mild steel or other nonhard metal. iowever, this quickly results in scuffed lower edges, very often almost like saw teeth, when the soft metal of the club engages rocks, etc. Considerable cost would be involved in trying to make a complete golf club head out of tool steel and of trying to harden the lower edge thereof because the material would cost much more than mild steel, the forging and machining cost would be appreciably greater, and special and almost impractical problems would be involved in just trying to harden the lower edge. Similarly, special problems are involved in trying to harden just the lower edge of a mild steel because only a skin or surface hardening can be effected with cyanide or case hardening treatment which would be quickly removed when the club head is polished, and because a pack hardening would leave the lower edge so brittle that it might crumble.

It is an important object of the present invention to provide golf irons in which the entire striking face may be of mild steel or other soft material to insure a sweet feel, and which may have a hard lower edge which will not scuff and cut into the ball. A feature resulting from the attainment of this objective includes the pro vision of a harder or hardened bottom plate which may be easily secured to the lower section of the golf head.

With certain types of golf irons it is desirable to have a connection between the shaft and the head which may be reached from the bottom of the club. However, such connections usually leave a large and unsightly opening, or when plugged very often result in the plug later falling out which changes the weight and balance of the club and results inan adverse appearance. Such an opening also allows water to adversely seep into the hosel and shaft connection.

It is an object of the present invention to provide a golf club which may have the advantages of an open bore at the bottom of the club leading to the shaft and hosel connection and which may be sealed in a permanent satisfactory and good-looking manner. I

An important feature of the present invention is the provision of a bottom plate for golf irons which advantageously seals or closes the bore for the hosel and shaft connection.

Other objects, features and advantages will appear hereinafter.

,Before describing the present" improvements and mode of operation thereof in detailit should be understood that the invention is not limited to the details of construction and arrangement of parts shown in the accompanying drawings, which are merely illustrative of the present preferred embodiments, since the invention is capable of other embodiments, and the phraseology employed is for the purpose of description and not of limitation.

Referring first to that form of the invention shown in Figs. 1 through 5, the golf iron 29 comprises a two-part golf head2l including a blade 22 with a preferably integral hosel 23. The hosel is provided with a bore 24 preferably slightly tapered, adapted to receive a golf club shaft '25 of any usual construction. The shaft may be forced or sweated into the bore 24. It may also be secured thereto by a crosspin 2B, or it may be wedged and held in place as by a taperedplug 2T insidethe shaft, which is drawn in place by a screw 28 inserted through a hole 29 at the bottom of the head 2!.

the cross-pin 26 is employed.

Now, it should be particularly noted that'the blade 22 is incomplete at the lower part thereof as may be seen best in Figs. 1 and 3,and is fashioned in a particular manner to advantageously receive and hold a bottom plate 39, as shown particularly in Fig. 4.

To the latter end the present invention particularly contemplates the provision of a base 3| adapted to receive a seating surface 32 on the bottom plate 36 and is further provided with depending lugs 33 adapted to envelop sides 34 of a projection 35 to prevent longitudinal shifting of the bottom plate on'the blade, and to engage rear walls 39 of the bottom plate 30 to locate and maintain the front face 31 of the plate in proper alignment with a face 38 of the blade 22. Further, the depending lugs 33 act as a fulcrum to translate any striking force applied against the lower edge of the bottom plate, as indicated by the arrow A, into a substantially arcuate line of force, as indicated by the arrow B in Fig. 2, to absorb the force and to minimize the shearing action which might otherwise be imposed upon the holding screws 39. The bottom plate 39 is preferably provided with an upwardly extending projection 49 adapted to fit into a suitable recess 44 at theback of the blade 22. The entire bottom plate 30 may be suitably secured to the blade 22 as by a force fit between the projection 139 and recess 4| and/or by screws 39 located and tightened in suitable holes 42 in the bottom plate 30 and threaded into holes 43 of the blade 22. p

It should be particularly noted that the proJection 48 on the bottom plate 39 isprovided with a plurality of preferably tapered socketswhich may be left empty or which may be filled with weights 44 of lead or other heavy material in order to impart the desired weight characteristics to the club. It should be particularly noted that this weighting arrangement is provided at or near the normal sweet spot (best playing center of the club head); .Thus, if a normal player.

buysa set of light weight clubs embodying this The latter results in a stronger and more satisfactory'looking hosel than when invention and wishes to increase the weight of the club heads in the set it is merely necessary to disconnect two screws 39 and insert a weight 44, which may be in the form of a slug in the center socket45 of the projection 4|. Alternatively, if he wishes a little more weight he may insert lead or other heavy slugs 44 in the two outer holes l'and 4'! alone or in conjunction with the slug-in the center hole 45. Furthermore, if a player purchased a light set of these clubs and desires to get, more weight into the toe or into the heel of the club in order to cause the club to overcome an inherent hook or slice playing characteristic, it is merely necessary to place a slug into the outer or inner holes 45 or 45, de-

pending upon theyclub characteristic desired. If it is desired to keep the sockets closed normally this may be done by including slugs made of wood, magnesium, aluminum or other light material which may be replaced with slugs of lead or other heavy material in order to accomplish the weighting hereinbefore described.

Further weighting of the club may also be achieved according to the present invention through the provision of a plurality of holes 48 throughout the main part 49 of the bottom plate 35!. Lead or other slugs 59 may be dropped into these holes at any desired points longitudinally of the club head in order to achieve weighting near the center of the club or toward the heel or toe as desired. Preferably these holes 49 are slightly tapered so that these slugs may be 1 knocked out by merely tapping the bottom plate 39 when it is disassociated from the blade 22. They are securely held in place by the blade when the bottom plate 39 is secured to the former as by the screws 39.

The bottom, plate 30 serves as an effective means for closing the bore 29 at the bottom of the club head and serves as a ready means for effecting access, if it is desired to disconnect the shaft for any reason, as for example when it is desired to replace one length or type of shaft for another. I

It should also be particularly noted that the bottom plates 30 may be made witha comparatively flat lower surface 5| relative to the seating surface'32, which would result in an assembled club of substantial upright lie, or may be formed with a lower surface at a greater or more substantial angle relative to the seating surface as indicated by the dot-and-dash lines to provide an assembled club with a low lie; This is a very important feature because with it the manufacturer may make a very large number of complete golf irons (excepting only the bottom plate) and need merely add low lie plates to the club assembly or medium or upright lie bottom plates to the otherwise complete clubs in order to meet field requirements. This can be done without inconvenience by merely stocking the divers bottom plates and overcomes the usual delay of some six to eight weeks encountered when the usual solid head golf irons of various lies must be processed from the point of a special forging.

The same holds true in connection with the manufacture of light, medium and heavy weight clubs and the manufacture of heel or toe weighted clubs for reasons pointed out hereinbefore in detail.

In its preferred form an insulator 54 of rubber, zinc, fiber or other vibrationand noise-ab sorbing material, as shown in Fig. 5', may be interposed between the surfaces 32, 3t, 55 and/or 55 of the bottom plate and immediately adjacent surfaces of the blade 22. i

Figs. 6 through illustrate another form of the present invention embodying the features and advantages just described in detail in connection with Figs. 1 through 5, differing therefrom primarily in the provision of a modified 'form of bottom plate. It includes a modified form of connection between the bottom plate BI and blade 22a which is adapted to receive an upstanding projection 63, on the bottom plate 6|. The recess 62' and projection 53 may be of greater depth and height respectively, as shown by dot-and-dash lines E4 in Figs. 7 and 9 particularly.

It should be noted that in this form, and all forms of this invention, the outer extremities of the bottom plates are curved and meld or curve into the regular curved contour of the ends of th main body of the blade so that there will be no projecting edges which would cut into the ball.

The projection 63 may be forced into'the recess 62 to hold the bottom plate Bl to the blade 22a and/or may be held therein by one or more screws 65., as shown in Fig. 8. The projection and associated construction provide a sturdy connection between the bottom plate and the blade, prevent any shearing strain from being imposed upon the holding screws 55, and prevent a direct blow or shock on the screws'which would tend to loosen them. It should be particularly noted that the projection 63 may be provided with a plurality of sockets 66a, 66b, 66c, 66d and 66a adapted to receive lead or other heavy weight slugs 61 in order to change a light weight club into a heavier club and/or toweight the toe or heel sections of the club as desired. For example, if it is desired to make a light weight club sli htly heavier the 'center socket 66a is filled with a slug 6! which has the weight at or near the sweet spot 68 of the club. Further weight may be added by placing'slugs in the sockets 65b and 660. If it is desired to merely weight the toe of the club one or both of the sockets ative to the blade 2211 it is merely necessary to provide insulator plates 69 and 10 between the projection 63' and seating surfaces TI and 12, as

shown in Fig. 7A.

It should be particularly noted that this form of the invention provides 'a single bottom plate with which it is possible to obtain a plurality of different lies in the one club and with the same parts. Fig. 6, for example, shows the bottom plate 6| assembled to the blade 22a in such a manner that the club shaft is at a substantial angle to the ground, see line (notice thick section of bottom plate near toe), to provide a club with a low lie. By merely reversing this same bottom plate in the same blade 22a, as shown in Fig. 8, the thick section of the bottom plate may be brought near the heel of the club and the thin section thereof near the toe in order to move the hosel and the shaft into a more near- 1y vertical position relative to the ground and thereby convert the same club into one having a substantially upright lie, as shown by line 16.

It should be noted that this form of the inventlon has a feature characteristic of the first form in efiec'tlocking theweighting lugs 61 in the sock ets 66a, 65b, 66c, 66d and 65e of the bottom plateifil. This is accomplished through the provision of. sidewalls .TI' and 18. and bottom 19 of the recess 62 enveloping and holding the lugs 61 in the sockets 65a, 66b, 66c, 66d and see. ThiSTStlllCtllIGlS'SllCh' that loose slugs may be dropped into the sockets and will be eifectively held or locked infplace by the walls.

Thatform' of the invention shown'in Figs. 11 through 17 is sim'ilarto the forms just described in detail, differing therefrom primarily in the provision of modified forms of bottom plates and BI which are, in efiect, inserted into the base of the blade 22b through the provision of avertically extending socket.82 suitably formed in the base. of the blades. As shown in Figs. 11 through 13 particularly, the bottom plate 83 has a bottom section 83 which extends completely transversely across the bottom of the club to complement the blade 22b and with the latter to form a complete club head Zia. The bottom plate 80 further includes a projection 84 adapted to fit into a deeper recess 85. This type of connection is very sturdy and prevents the bottom plate from loosening relative to the blade 22b evenv though heavyiblows or shocks are imposed thereon. It may be merely forced into the blade or it may be held' therein by suitable pins or studs 86 which pass through the blade and partially enter the bottom plate 80, as shown in Figs. llthrough l3.-

As with the other forms of the invention the bottom plate may be provided with sockets 81a, Bic, 81d and Ne adapted to be empty when it is desired to have a light weight club and to be filled varying amounts as with lugs 88 when itis desired to have heavier clubs. Further, the initial weighting may be in the center socket 310 or sockets am, 81b and 81d in order to achieve the major weighting, near the sweet spot of the club; or slugs may beadded in all the sockets 8M, 8%, S'lc, did and tile in order to efiect a balanced weighting of the club when a heavy club-head is desired. Furthermore, one or both of the sockets B'Iaand 812) may be filledwhen it is desired to have a toe weighted club and one or both of;the sockets 81d and 8'le may be filled when it is desired to have a heel weighted club, to overcome certain adverse playing characteristicsr I The base section 83 of the bottom plate 89 may be made thicker or thinner toward the toe section, as shown'by dot-and-dash lines AA andB B, in order to have plates of such construction convert the golf club from an upright lie into. a low lie club respectively, as will be appreciated from the detailed description hereinbeforel,

Also, this bottom plate 69, and any of the bottom plates herein disclosed, may be made of a hard material, hardened tool steel, or a mild steel heat treated to withstand scuifing 0f the bottom edge of the club with the usual adverse results, and the remainder of the club may be left soft in order to give the desired sweet feel when the ball is struck. Thus, savings in material and heattreating costs can be effected with the present invention.

That form of the invention shown in Figs. 14, 15zand 17 is just like'the form shown in Figs. 11, 12 and'13 described in detail, excepting that therbase section terminates on the same plane asithebackzof therecess 8.5: (see 15) instead.

of extending completely transversely across the bottom of the base of the blade, as shown in Figs. 12' and 13. The latter form is advantageous over the form in Figs. 14 and 15 from a manufacturing standpoint since it is easier to machine. However, that form shown in Figs. 14 and l'does provide a stronger support forthe bottom plate 8 l. t I

That formof the invention shown in Figs. 11 through 13' may have the bottom plate insulated from the blade by merely'placing an insulator Q0 of zinc, fiber, rubber or other soundand vibration-absorbing material about the projection 84 and by having the width of the recess '85 sufficient'to accommodate the same, as will be readily appreciated.

Use of the flat plate 9|, as' shown in Fig, 16, interposed between-the seating surfaces 92 and 93 and adjacent the underside of the blade 'mem ber 2211 is optional but does tend to further insulate the bottom'plate 89 from the blade 2%, and minimize vibration or shock reaching the players hand, especially if the bottom plate strikes a stone or the like.

Similarly, and if preferred, the bottom vplate SI of Figs.-14 and may be provided with an insulator 524, as shown in Fig. 17, havinga looped section 95 adapted to envelop the projection 84 which fits into the recess 85, and liaving a depending apron 95 adapted to back up a rear wall 9'! of the base section 98. Optionally, the forward wall 99 of the looped section may be provided with a horizontal extension I60 adapted to fit between the seating surface llll of the bottom plate 8i and a lower wall I02 of the blade 22b. Use of the insulating interponentsis optionaljthe Figs. 11 through 15 disclosing the structure without the insulator. However, as will be readily appreciated, it is merely necessary to make the various recesses which accommodate the bottom plates 80 and/or 8| slightly larger, equivalent the thickness of the insulators 90 or 94 used in order to include the same in the structure (see Figs. 7 and 7A which are illustrative).

The present invention provides a new economical and advantageous method of manufacturing golf clubs, including the steps of manufacturing a large quantity of like and nearly complete golf clubs toward the point of final assembly; making bottom plates of divers lie and weight characteristics; and assembling selected bottom plates to the like and nearly complete clubs. to provide complete clubs with divers and desired lie and weight characteristics. The method also includes making a quantity of like and nearly complete golf clubs toward the point of final assembly; making a quantity of like reversible bottom plates; and then weighting and assembling said bottom plates to the like and nearly complete clubs to provide complete golf clubs with divers lie and weight characteristics.
